General chemical structure of a dithioketal

In chemistry, a thioketal is the sulfur analogue of a ketal, with one of the oxygen replaced by sulfur. A dithioketal has both oxygens replaced by sulfur.

Thioketals can be obtained by reacting ketones or aldehydes with thiols.

Ketones can be reduced at neutral pH using the thioketal method.[clarification needed] The thioketal prepared from the ketone can be easily reduced by catalytic hydrogenation using Raney nickel in a reaction known as the Mozingo reduction.
